It allows a developer to interface a Windows, Linux, or Mac OS X PC via USB to a downstream embedded system environment and transfer serial messages using the I2C and SPI protocols. It outputs a table with the list of detected devices on the specified bus. i2cbus indicates the number or name of the I2C bus to be scanned, and should correspond to one of the busses listed by i2cdetect -l. After deploying our dotnet Core application to a Linux server it can be difficult to troubleshoot… set -x: Display commands and their arguments as they are executed. initcalls are used to initialize statically linked kernel drivers and subsystems and contribute a significant amount of time to the Linux … $ bash -x script-name $ bash -x domains.sh. flash.sh This is a official tool to flash jetson platform. could anybody please help me what is meant by this [.0, .1, .2] in i2c command executed in uboot prompt.
